    Abstract: An apparatus includes a magnetic adjustment lens (116) positioned at the electron beam path between the electron source (102) and sample (124), the magnetic adjustment lens excited by an electric coil, and a permanent magnet lens (118) positioned below the magnetic adjustment lens to focus the electron beam onto the sample surface, the permanent magnet lens excited by one or more permanent ring magnets enclosed except on a bottom surface by a magnetic field conductor. The magnetic adjustment lens may be excited to eliminate magnetic field leakage of the permanent magnet lens.

    Abstract: A system and method for rapidly processing a specimen. The method includes generating a plurality of charged-particle beams travelling substantially along respective axes of an array of charged-particle beam columns by providing each beam column with two permanent magnets having at least one magnetic dipole disposed in a plane perpendicular to the axis. The trajectory of the beams is independently controlled and the beam is focussed onto the specimen using additional correctional coils. The beams are deflected while maintaining incidence of the beam on the specimen parallel to the axis. Preferably, the charged particle beams include non-crossover charged particle beams. Preferably, the method further includes detecting charged particles scattered from the specimen using a detector at least partially immersed in a magnetic field, by utilizing at least in part the magnetic field.
